Indeed. When Knuth found was informed of this problem in a random number generator of his, he fixed it: http://news.ycombinator.com/item?id=3730348 http://news.ycombinator.com/item?id=3730348 There is an obvious use case for this: you have a test which is run N times where you want to have different random numbers in each run, but you also want to be able to go to run X and debug it without running all the previous ones.
